1. An environmental control unit comprises: a housing that includes a first end, a second end, a sidewall that extends between the first end and the second end, and a divider panel that is surrounded by the sidewall and segregates an interior space of the housing into an air-handling portion and a condensing portion; a blower disposed in the air-handling portion; a heat exchanger disposed in the air-handling portion; a compressor disposed in the condensing portion; a fluid circuit including a refrigerant line that connects the heat exchanger to the compressor; and an electronics box that is mounted on the divider panel and houses a control board, the electronics box being provided with two independent modes of cooling; wherein the electronics box includes a first side that faces the blower and a second side that faces the compressor, and the first side is cooled by airflow from the blower and the second side is cooled by a coolant line that is connected to the refrigerant line.
